The other option, of course, is to RP in third person. 'Ace says', 'Snooze gasped', etc. Like we do in emails. Then, I suppose, we wouldn't have to be constantly signing in and out of multiple accounts, which is the main reason for annoyance, really.

I think it would be like, sometimes the third person works better for some verses more than others? Say, the batverses don't lend well to it, and slaveverse it better with third person with dialogue - told like a story - and things like Victorianverse are better suited to having them all talk to each other directly. But I reckon we'll figure that out as we go along.

No doubt. Let's leave the character accounts for now, then? We can try just putting at the top of the post who the character is, or using colours, or the post title, or whatever. We know which characters we control, after all.
